A diagnosis system composed of a fluoroscopic apparatus for obtaining a fluoroscopic image of an internal body be radiating x-rays to the body, and an endocopic apparatus for obtaining an optical image of the internal body part to be observed by inserting an insertion section of the endoscope into the body. In an operating section of the endoscope, a fluoroscope operating section for operating the fluoroscopic apparatus is disposed. Operation signals from the fluoroscope operating section are sent from a communication I/F of an endoscopic processor to the fluoroscopic apparatus. The fluoroscoptic apparatus receives the operation signals with a fluoroscopic processor and controls a fluoroscopic table.
